Question

the parts of rays of red and blue light passing through a glass prism. what can be deduced about the index of refraction of glass for red and blue light?

Answer 1

Answer:

The formula for refractive index is  

sin(I)/n = sin(r)

Here 'I' is the angle if incidence and e is the angle of refraction.

Explanation:

The slower speed means a larger index while a higher speed of the light corresponds to the lower index of refraction.  

As 'n' for red is smaller than 'n' for blue and also it has a shorter wavelength, so, red has always a lower index of refraction.
